Hi, my name is
Y Lau.
I create interesting things for the online world.
I am an Internet Product Manager, focused on creating engaging digital experiences (occasionally developing applications). Currently, I am dedicated to building exceptional products in the Web3 space. Github.
About Me
Hello! My name is Liu Yu, and I enjoy creating interesting things on the internet. My interest in the internet began in 2011 when I, along with three classmates, developed an online travel data service platform. During the three years of running the company, we launched a travel platform and overseas social applications, gaining a lot of foundational knowledge and operational experience in internet products!
Fast forward to today, I am now a full-time Product Manager at a Web3 internet company. My current focus is on iterating the operations of a blockchain payment gateway project, providing users with an inclusive and ultra-fast payment experience.
In my spare time, I create self-media content related to public API service development, covering Web3, hardware development, and sharing the process of building.
Here are a few technologies I've been working with recently:
- Product Strategy
- Web3/DeFi
- Blockchain
- Figma
- Data Analytics
- Agile/Scrum
